STARTING UNIT FOR DIESEL INTERNAL COMBUSTION ENGINE Russian patent published in 1995 - IPC

FIELD: engine engineering. SUBSTANCE: starting unit has program device 1 whose information input is the input of the unit, actuating relay 2 whose contacts 4 are connected to the unit input used for connecting a battery and to the output of the unit, auto-generator 6, and control logical circuit 5. In addition, the unit can be provided with logical circuit OR 12 whose inputs are connected to the feeding bus of the unit and to the output of the unit. The output of the logical circuit OR is connected to the feeding bus of control logical circuit 5. The contact of the actuating relay is secured to the flat spring and mechanically coupled with the armature of the actuating relay. The output frequency of the auto-generator is equal or multiple to the natural resonance frequency of mechanical oscillation of the movable system of the actuating relay. EFFECT: enhanced reliability. 4 cl, 4 dwg
